Answer:

<h3>X=2</h3>

Step-by-step explanation:

Isolate x on one side of the equation.

3(x+2)=12

3(x+2)/3=12/3 (First, divide by 3 from both sides.)

12/3 (Solve.)

12/3=4

x+2=4

x+2-2=4-2 (Then, subtract 2 from both sides.)

4-2 (Solve.)

4-2=2

x=2

Therefore, the final answer is x=2.

If f(x)=6x-15 and f(a)=30, what is the value of a?<br> Please help
mariarad [96]

Answer:

a=7.5

Step-by-step explanation:

Given the function f(x)=6x-15 and the output 30 when x=a, we can write the equation:

6a-15=30

6a=45

a=7.5

We can insert the value of a into the function to verify the output equals 30:

f(a) = 6a-15

= 6(7.5)-15

=30

∴ We have verified that a=7.5

Hope this helps :)

Work out the percentage change when a price of £40 is decreased to £38
max2010maxim [7]

Answer:

5%

Step-by-step explanation:

38/40 = x/100

38*100 = 3800

3800/40 = 95

95/100 = 38/40

38 is 95% of 40 therefore the change is 5%

20 pts and a mark!!! A store is having a sale on jelly beans and trail mix. For 6 pounds of jelly beans and 2 pounds of trail mi
marysya [2.9K]

Answer:

The cost of Jelly Beans = $ \frac{5}{4} $

The cost of Trail Mix      = $ \frac{9}{4} $

Step-by-step explanation:

Given the cost of 6 pounds of Jelly Beans and 2 pounds of trail mix is $12.

Also, the cost of 3 pounds of Jelly Beans and 5 pounds of Trail mix is $15.

Call the cost of one pound of Jelly beans as J

And cost of one pound of Trail Mix as T.

Now, converting the given data to mathematical form, we would have:

$ 6J + 2T = 12  $

Dividing through out by 2 we have:

$ 3J + T = 6 \hspace{15mm}  .....(1) $

$ 3J + 5T = 15 \hspace{15mm} ....(2) $

To solve (1) and (2), subtract the two equations which will give us:

$ -4T = - 9 $

⇒                                            T = 9/4

Substituting the value of T in (1), we have:

$ 3J = 6 - \frac{9}{4} $

$ \implies 3J = \frac{24 - 9}{4} = \frac{(3)(8 - 3)}{4} = \frac{5}{4} $

∴                                               J  = 5/4

Is it possible for a composite number to have more then o e prime factorization ? and is it possible for a number to have no pri
sashaice [31]
1. No, because every prime factor can not be prime factorized again. It could have more factorizations, but at least one of the factors would be a composite number which is the product of at least two of the prime factors.
2. Prime numbers and 1 do not have their prime factorization.
